If I've said it once, I've said it way too many times. If you have a hard time finding recipes for certain powder/bullet combinations in published manuals, there's a good reason. It's not necessarily that it won't work, but odds are it doesn't work well and that is why they are not included in the published recipes. Powder/bullet manufacturers have already done that work for us. Sure, someone online probably can give you a single old published recipe or something they figured out on their own, but if it's so good, why isn't in published manuals? IMHO, PowerPistol is too fast for legitimate 240 gr .44 magnum loads. It will probably work well in low to moderate velocities and in .44 special or with light for caliber bullets in .44 mag.
